Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

SLG’s 2×4 high bay (370W) is reviewed for extreme-height lumen delivery (49,500 lumens), thermal control engineered for high-heat industrial duty, and wide-distribution coverage with 0–10V controls readiness so high-ceiling bays stay bright and uniform without hot-spotting, driver overheat drift, or dimming-zone mismatch.

Spec review focus:
Verified for extreme output at 49,500 lumens / 370W to support max-height industrial mounting where standard fixtures under-deliver at the task plane; verified for thermal management intent engineered for high-heat environments so lumen maintenance and driver stability hold under long duty cycles; verified for wide distribution to maximize floor coverage and reduce “striping” between fixtures in large bay layouts; verified for 0–10V controls readiness so dimming remains stable without flicker, dropout, or uneven response across a row when tied into sensors or building controls; verified for 120–277V input compatibility for standard commercial power conditions and common industrial service voltages; verified for “high-bay practicality” where high output and spread reduce fixture count pressure while still supporting control-based energy reduction.

Verified configuration:
On ultra-high-output high bays, layout and controls setup decide whether the space feels professional or chaotic: document mounting height, spacing, and aiming/orientation so the wide distribution doesn’t create glare bands or over-bright aisles. For 0–10V, standardize the dimming curve and sensor grouping—one fixture on a different high-end trim (or a different control zone) becomes the obvious brighter patch in the bay, especially at reduced light levels.
